Kooks GM 1500 6.2L Performance-Catted Header and Y-Pipe Kit (2019+) | 2863H420

A matched exhaust upgrade for your naturally aspirated 6.2

Bring Kooks long tube headers and a catted Y-pipe to your 6.2-litre GM truck as one matched upgrade. The 1-7/8" primaries, 3" collectors and 3-1/2" OEM rear outlet give you a clear specification for improving the front exhaust while retaining the rear system.

SKU: 2863H420

Headers and Y-pipe in one kit

The stainless steel Y-pipe is supplied with the headers and uses the rear outlet for the listed 6.2-litre configuration. You can keep a rear exhaust that uses the factory 3-1/2" interface, rather than adding a new cat-back to complete this purchase.

Choose Performance cats for a naturally aspirated build

This package uses standard Performance cats. They are intended for naturally aspirated applications. For a truck with a supercharger or turbocharger, choose a suitable GREEN-family catalyst package so the front exhaust matches the engine you are building.

Tuning for your exhaust upgrade

We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Contact us to discuss the right tuning route for your vehicle.
